When Bo and Carrie are on the dirt road about to jump the dismantled bridge, looking out from the inside there is NO rear view mirror, also there is no license plate on the back in the same section when he spins around.

When he first picks up Carrie she says "are we really doing 110?"

the speedometer says about 70-75, and the key is in the off lock position.

Also in the beginning credits it shows the bandit hitting the brakes, he has red boots on, no where else in the movie is he wearing THOSE boots.
